HIRAM W. HAYDEN, OF VATERBURY, CONNECTICUT, ASSIGNOR TO HOLMES, BOOTH & HAYDENS, OF SAME PLACE.

LAMP-BURNER.

SPECIFICATION forming part of Letters Patent No. 390,079, dated September 2,5, 1888.

Application filed September 26, 1887. Serial No. 250,733.

To all whom, it may concern:

Be it known that I, HIRAM W. HAYDEN, a citizen of the United States, residing at Waterbury, in the county of New Haven and State of Connecticut, have invented new and useful Improvements in Lamp-Burners, of which the following is a specification.

My present invention relates to oil-lamps of the class in which Arg-and burners are employed, and the purpose thereof is to simplify and improve the construction of parts, whereby a constant air-current is directed over the end of the annular wick-tube, to obtain a strong uniform flame of great brilliancy and volume, and to reduce in a very material degree the tendency of the burner to become overheated.

The invention consists in the several novel features of construction and new combinations of parts, hereinafter fully set forth, and detinitely pointed out in the claims.

In the accompanying drawings, Figure 1 is a central vertical section of an Argand burner for an oil-lamp with my invention embodied therein. Fig. 2 is a detail of the deflecting-ring removed from the lamp.

In the said drawings, the reference-numeral l designates the annular wick-tube of an Argand lamp-burner of any desired pattern, having an ordinary deiiector, 5f". The chimneyring 2 is provided with an inwardly-projecting annular flange, 4, the outer edge of which is formed integral with a vertical rim terminating in spring-fingers to hug the chimney, while the inner edge of said flange is formed integral with a bulbous perforated collar, 8, having at its lower edge a vertical serrated rim forming springlingers, (represented by dotted lines, Fig. 1,) which bear upon the outer wick-tube. The chimney-base 5 is composed of an annular flange resting on a foraminous air-distributing disk, 6, supported by the inwardly-projecting ange Land extending from said flange to and bearing against the outer wick-tube. rlhe chimney base or flange 5 is formed with an annulus, 7, which extends upward as far as the top ofthe wick-tubel, with which it is concentric. As shown in the drawings, this annulus is slightly contracted at its top relatively to the dimensions at the base;

but it may be of equal diameter throughout, 5o

or substantially so. vThe usual annular space between it and the wick-tube is not materially varied, and draft-openings 8 may be formed in its lower portion, as shown.

By forming the chimney base or flange 5 in- 55 tegral with the annulus7 the cost of manufacture is reduced and the device is rendered more simple in construction. In those burners where the annulus or cone extends above the top edge of the wick-tube and slightly 6o.

overhangs the outer tube the rising air-current ascending around the outside of the burner is suddenly deflected inward, and, further, this overhanging top of the annulus, he-

ing constantly in contact with the flange of the wick, becomes intensely hot and imparts its great heat to all other parts of the burner, making it too hot tohandle with the naked hand, and in many instances igniti ng the gas formed in the lamp-reservoir above the oil 7o and causing it to explode. I have found in practice that this objection may be practically overcome and that better results may be obtained by carrying the annulus no higher than the top of the wick-tube and giving it a cylindrical form, or, in other words, making it of substantially equal diameter throughout. I may, however, allow a moderate degree ofcontraction at the top without essentially modifying the results obtained, and the annulus may 8o be spun with a circumferential shoulder, 9, about half-way of its height, that portion of the annulus lying above the shoulder being of less diameter than the part below; but in no instance should the top of the annulus project s 5 concentric wick-tubes 1, the chimney-ring 2, 9o

provided with the inwardly-projecting flange 4, formed integral with the depending perforated collar 3, having upwardly-projecting spring-fingers which hug the outer wick-tube,

the foraminous disk 6, resting on the Bange of the chimney ring, and the chimney base 5,

resting on the foraminous disk and formed integral with the annulus 7,which rises and terminates in :n angeless top edge at the top edgesof the wick-tubes, substantially as described.

2. An Argand lmnp-burner consisting of the concentric Wick-tubes l, the chimney ring 2, formed integral with the Vertical chimneyholding fingers, and the inwardly-projecting lflange 4, formed integral at its inner edge with the depending perforated collar 3, having 1.11 upwardly-projecting serrated rim formed Wit-h springfngers which hug the outer Wiektube, the foramiuous disk 6, resting on the shoulder of the ehimney-ring and extending therefrom to the outer Wick-tube, and the chimney base or flange 5, resting on the foramiuous disk and i 5 formed integral with the annulus 7, which is perforated above the disk and rises and termihates in a angeless top edge at the top edges of the wiek-tubes, substnntirillyas described.

In testimony whereof I affix my signature in 2c presence of two Witnesses.
